If you were to build 5e from the ground up (which Wizards seems to be sort-of doing), where would be your starting point? Everyone has his/her preferred version - mine is BECM. But even I would entertain starting from a 1e, 2e or 3.x "base" and building from there. Or would it be easier/better to start with 4e and try to retrofit elements from previous versions? Personally I think that 4e was too much of a departure on many fronts; but even I can see the benefit of Some of what was done.
What should be (or should have been) the starting point.. the foundation?
